When my nephew got married, Alan was just shy of his 5th birthday, and the wedding reception was the biggest, best party he had ever been to. He loved the music, and danced with complete abandon. Five-year-old boys do just about everything with complete abandon. Of course it's all on video, and you can hear Alan say, "Watch me, Dad!" I love that. He didn't care what anyone around him was doing. He didn't care if he was doing all the 'right' steps. His dad was there watching, and that was all that mattered.
